[KERNEL] protect read-only access to server list
This patch completes the changes from the last commit [1] and protects
in addition the read-only access to the alternative list of new servers.
Otherwise a race condition between ioctl ADD_SRV/REM_SRV (process
context) and dnbd3 discover thread would be possible since the
'new_servers_num' field is changed in both contexts.
[1] - DNBD3 commit db5a93a43fea2aa3c3bbaf8c48d238e60d834676
